The manifestations of life-threatening digoxin toxicity include ventricular arrhythmias such as ventricular tachycardia or ventricular fibrillation or profound and progressive bradyarrhythmias not responsive to atropine.
When do you give Digibind?
Specific indications:
Serum digoxin level >15 ng/mL (19.2 nmol/L) at any time, or >10 ng/mL (12.8 nmol/L) 6-hours post-ingestion (independent of symptoms). Acute ingestion >10 mg digoxin in an adult. Acute ingestion >4 mg digoxin in a child.
Is Digibind still on the market?
The Digibind brand name has been discontinued in the U.S. If generic versions of this product have been approved by the FDA, there may be generic equivalents available.
Is Digibind the same as DigiFab?
Although Digibind and DigiFab are equivalent in their digoxin-binding activity, the antigens used to produce these Fabs are different.
How quickly does Digibind work?
Ordinarily, following administration of DIGIBIND (digoxin immune fab) , improvement in signs and symptoms of digitalis intoxication begins within one-half hour or less.
Does Digibind increase digoxin levels?
The total serum digoxin level increased significantly after initiation of Digibind therapy and peaked at 125 ng/mL, but the free serum digoxin level immediately decreased to nontoxic levels immediately after initiation of Fab therapy.
What is the antidote for digoxin?
In the case of severe digoxin intoxication, an antidote digoxin immune Fab (Digibind) is available. Digibind binds and inactivates digoxin.
In which poisoning the Digibind is used as an effective antidote?

What is a normal digoxin level?
Therapeutic levels of digoxin are 0.8-2.0 ng/mL. The toxic level is >2.4 ng/mL.
When do you draw digoxin after Digibind?
At least 6 to 8 hours are required for equilibration of digoxin between serum and tissue, so absorption of the last dose may continue from the intestine. Therefore, serum measurements may be difficult to interpret if samples are drawn soon after the last digitalis dose.

How fast does DigiFab work?
In a comparative pharmacokinetic study of DIGIFab and Digibind administered in healthy volunteers, DIGIFab rapidly reduced serum free digoxin to undetectable levels within 30 minutes, and serum digoxin levels were reduced to undetectable levels in all subjects.
When do you take digoxin immune fab?
Digoxin immune Fab is indicated for the treatment of life threatening digoxin toxicity in patients with manifestations of severe toxicity. It is NOT indicated for mild cases of digoxin toxicity or in cases of elevated serum digoxin concentrations in the absence of signs and symptoms of digoxin toxicity.
What are the signs and symptoms of digoxin toxicity?
Some early warning signs of overdose are confusion, loss of appetite, nausea, vomiting, diarrhea, or vision problems. Other signs of overdose are changes in the rate or rhythm of the heartbeat (becoming irregular or slow), palpitations (feeling of pounding in the chest), or fainting.
